Enabling the web listener

A web listener is software that accepts connections from web browsers on the LAN configured to use the ProLiant DL320 Security Server as a web proxy server. The web browser sends requests to connect to the Internet directly to the IP address on the ProLiant DL320 Security Server, listening for outbound web requests. Some advantages of configuring the web browser to use the ProLiant DL320 Security Server as a web proxy include:

•The client computer connecting to the server does not rely on its default gateway configuration to connect to the Internet. The client computer must only know the route to the internal IP address of the server.

•Non-Microsoft®operating systems can authenticate with the ProLiant DL320 Security Server.

•You can use RADIUS to authenticate web browsers connecting through the web proxy. Microsoft® implements RADIUS as part of its IAS servers, which is a service available on Microsoft® Windows Server™ 2003 and Microsoft® Windows® 2000 Server family products.

•You can configure:

•A connection time-out for web browsers connected to the server

•A limit on the number of simultaneous connections

To enable and configure the web proxy listener:

1.In the scope pane of the ISA Server 2004 management console, expand your server name, expand the Configuration node, and then click the Networks node.

2.In the details pane on the Networks page, click the Networks tab.

3.In the list of networks, right-click the internal network, and click Properties.

4.In the Internal Properties dialog box, click the Web Proxy tab.

5.Select the Enable Web Proxy clients checkbox.

6.Select the Enable HTTP checkbox.

7.Verify that the default port number in the HTTP port text box is 8080.

8.Click the Authentication button.

9.In the Authentication dialog box, verify that the Integrated checkbox is selected.

10.Select the Basic checkbox.

11.Click Yes in the ISA Server Configuration dialog box warning you that passwords are transmitted in clear text when sent by means of basic authentication. Clear text communications can be captured

Microsoft Internet Security and Acceleration (ISA) Software specifications

HP Microsoft Internet Security and Acceleration (ISA) Software is a robust network security solution designed to safeguard business environments by offering a versatile platform for secure internet access. ISA Server integrates multiple functionalities that are essential for modern enterprise needs, helping organizations manage and protect their network infrastructure.

One of the main features of ISA Server is its firewall capabilities, which provide an essential barrier between internal networks and external threats. The software utilizes intelligent packet filtering to analyze incoming and outgoing traffic, ensuring that only legitimate communications are allowed while blocking potentially harmful activity. This helps to mitigate risks associated with external cyber threats and unauthorized access.

Another key feature is the built-in web caching technology. ISA Server improves network performance by caching frequently accessed websites and content. This reduces bandwidth usage and enhances response times for end-users, leading to increased productivity. By storing copies of web pages, ISA Server can serve them quickly to users, allowing enterprises to optimize their use of internet resources.

ISA Server also includes a powerful Virtual Private Network (VPN) feature, enabling secure remote access for employees. This technology supports secure connections over the internet, allowing users to access the corporate network and resources from anywhere in the world. The VPN capabilities ensure data encryption during transmission, protecting sensitive information from interception.

Moreover, ISA Server incorporates integrated threat management tools, which offer insights into potential security issues. These tools provide logging and reporting features that allow administrators to monitor traffic patterns and detect anomalies. This functionality is critical for identifying and responding to potential security breaches in real-time.

In addition to these features, ISA Server supports application-layer filtering, which enhances security further. This allows organizations to control access to specific applications and services while ensuring that malicious content cannot infiltrate the network.

Overall, HP Microsoft Internet Security and Acceleration Software is a comprehensive solution designed to address the complexities of network security in today’s digital landscape. Its combination of firewall protection, web caching, VPN capabilities, and application-layer filtering makes it an invaluable tool for organizations looking to secure their internet connectivity while optimizing performance and user experience. By leveraging advanced technologies and characteristics, ISA Server empowers businesses to operate safely and efficiently in an interconnected world.
